Cheers mate.

Everything seems to work just fine without it. Had it done during summer and no dramas with the aircon. I thought there was an issue but just had the revs set a bit low at idle and with the aircon on. Upped it all to where it should be and it came good.

Plenty of room there without it. The standard alloy bar allows pretty good airflow through it too. A standard bar would pretty much cover the whole ic where I have it mounted I reckon.
